As will be'seemfrom-Figs. lto 3, inclined cross flues orconduits 4 are provided according to v this;invention in: the parti--.; tion 3 which separates the gas-flue 1 from theairfiue 2, the conduits '4 being inclined in opposite directions in such manner that they rise alternately from right to left and from left to right; Owing to this arrangethe draft inducedbythe chimney acting in the. fines 1" and 2, will result the heating" gas being alternately drawnf frorn the fine from the flue 2 into the flue 1' through the inclined transverse -conduits, and in that Way's. gradual and complete mixing of the ases and I the combustion fair is m'snrmi. ach transverse conduit 4 isprovided at its month with a sharp edge-4 into the "flue 1f 0172 this edge itdividing the current'of heating gasor air which strikes j 1 clined; conduits 4. in the partition 3; can either bestraight as in- Fig.

asses from the horizontal tlne 12 into the bottom portion of the heating-gas supply tlue t5 and into the air supply ilue 13 which is separated from-thc tluo 8 by the partition 14. In the partition 14. are provided at certain distances perforations 15 by means of which communication is established between the heating-gas supply tlue Sand the air supply tlue 1d. To eil'eet preliminary mixing of the heating gas and combustion air, partitions 16 or 17 are provided in the bottom portion of the tlues 8 and 13, as shown in Figs. 6 to 8, in which partitions are arran ed alternate inclined conduits 18 or 19. Owing to this arrangement, the mixture of gas and air formed in the bottom portion of the iiucs 8 and 13, is carried alternately in the direction indicated by the arrows, and

thus subjected to a preliminary mixin To insure the best possible mixture between the gas and air, and to enable gradually increasing combustion, to take place in the heating flues 9, partitions 9.0 are built into the front portion of the longitudinal flues 9, these partitions being provided with alternately inclined transverse conduits 21. The mixture of "as and air, etfeeted in the bottom )ortion of the tines 8 and 13 does notthereore burn suddenly at the point where the heating gases meet the air but owing to the perforated partitions 16, 17, this mixture is first subjected to a preliminary mixing then rises in the lines 8 and 13, and by reason of the transverse conduits .21 in the partitions 20 is burned in theheating tines t in a gradual and uniform manner. In that way, a very uniform heating of the furnace chambers or retorts 10, between which the heating tlues 9 are formed is insured, and such uniform heating is of great importance for the process of distillation which takes place in the retort or chamber, and for the products thus obtained.

In the construction of furnace shown in Fi s. 4 to 8, the heating gases escape through a discharge flue 22 arranged at the hack oi the furnace.

Figs. 9 and 10 show a modified construction of the arrangement in which the front portion of the longitudinal heating ilue t) is provided with a partition .Z-t having two superimposed series of inclined transverse conduits 95 or .26 rising alternately in oppo- BEST AVAILABLE COPY site directions, whereby a thorough mixin of the gases and of the air is insured throughout the whole height of the ilue S).

The alternately inclined transverse conduits 18, 1S) and 21 of Figs. 4 to 8, and the like conduits 25, 26 of Figs. 9 and 10, are provided at their inlets with sharp edges of the same character as the edges 4 of the channels 4 shown in Figs. 1, 2 and 3; in each case, these edges, by projecting into the adjacent channels or ilues separated by the partitions 3, 16, 17, 20 or 24 respectively, will as it were cut or skim thin layers from the gas or air or mixture current ilowing in such channels or tines, and cause such layers to be deflected into the inclined or oblique conduits or ducts.

It will be understood that my invention is not limited to the actual arrangements above described and illustrated, and that the constructional details may be varied without departing from this invention.

What I claim is 1. In "as-generating furnaces, the combination with a heating gas flue and a combustion air flue, of a partition separating said fines from. each other and rovided with transverse conduits alternatey inclined in opposite directions and having at their mouths sharp edges projecting into said tlues, said conduits forming connections between the gas fiue and the air fine.

'2. In a device for roducing a uniform mixture of fluids, adjoining tines, a longitudinal partition separating such tlues, said partition being formed with oblique transverse conduits connecting said tlues at different points of their length and inclined alternately in opposite directions, the partition being also formed with projecting edges at the inlets of said conduits.

3. In a device for producing a uniform mixture of iluids, adjoining tlues, a partition separating said tlues and provided with oblique transverse conduits connectin said tlues, said conduits being inclined alternately in opposite directions and having projecting edges at their inlets.

in testimony whereof I have signed this specification in the presence of two subscribing witnesses.
